I thought multi-signature wallets were extremely safe. My understanding of multi-signature is that it requires many people to sign and confirm before it can be used. I didn’t expect it to be hacked. Did I misunderstand it? SlowMist Yuxian: WazirX was stolen due to a hack of a certain ETH hot wallet address multi-signature

SlowMist founder Yuxian Yu X said in a post: "Indian exchange WazirX was stolen over 230 million US dollars because of the hack of this ETH hot wallet address multi-signature:

0x27fd43babfbe83a81d14665b1a6fb8030a60c9b4

It was 4/6 multi-signature before, it seems that all related private keys have been compromised.

The attacker replaced the logic contract of the multi-signature contract with a malicious contract prepared 8 days ago through related transactions about 3 hours ago, and then carried out subsequent batch theft operations."
